+ * @brief The LtsMessageDialogHelper class cannot be exported and only is a helper class which is actually instantiated, shows the LtsMessageDialog.
+ * To provide the blocking call to showMessage (call with return type), an event loop is created and exited when the user has selected a button to close the dialog.
+ * If the behaviour is non-modal, closing the Dialog by clicking outside of it will return Button::Cancel.
